The latest Ipsos Mori political monitor found that half of Labour supporters are now dissatisfied with the way that Corbyn is doing his job as Labour leader.

This is the highest level yet of dissatisfaction with Corbyn among Labour supporters since he became leader in September 2015.

The Islington North MP retains the support of 41 per cent of Labour supporters, with nine per cent answering don't know.

The figures are more promising for Theresa May, with 53 per cent of adults satisfied with her as prime minister, up eight points from January.

Some 36 per cent of voters are dissatisfied with May, giving her a net rating of plus 17.

“The historical contrasts look good for Theresa May, but much more alarming for Jeremy Corbyn,” said Gideon Skinner, head of political research at Ipsos Mori.

“The prime minister is enjoying a better honeymoon at this stage then her two immediate predecessors, David Cameron and Gordon Brown. However, Corbyn’s ratings as a Labour opposition leader almost 18 months in are closer to Michael Foot’s.”

The research appears to confirm that Corbyn’s stance on the Brexit bill has alienated a number of his own voters.

Ipsos MORI interviewed 1,044 adults between February 10 and 14. Corbyn frustrated many Labour members by ordering MPs to vote to trigger Article 50 on 8 February.

The Labour was then widely ridiculed for responding to the passing of the Brexit bill with a declaration that "the real fight starts now".

The latest polling will refocus attention on the race to replace Corbyn as even allies of the leader are said to be planning the succession to safeguard his legacy.

Keir Starmer and Emily Thornberry are thought to be potential contenders for the Labour crown, should Corbyn call it a day.

But some of the leader’s closest allies hope that the recently-appointed shadow business secretary Rebecca Long-Bailey could step into his shoes if needs be. In particular, shadow chancellor John McDonnell is known to be a huge fan of the Salford and Eccles MP.

Others on the Labour left – including the influential Guardian columnist Owen Jones – appear to favour Clive Lewis as the party’s next leader.
